Event Details & Abstract: 

In massive galaxies and in clusters of galaxies, the thermodynamic state of the circumgalactic gas seems to regulate whether or not star formation is occurring in the central galaxy. I will discuss the observational evidence for this claim. I will also discuss implications for lower mass galaxies if regulation via precipitation triggering plays an important role in those galaxies as well. Physical predictions of this model will be presented.
